Copernicus Sentinel-2 Images Now Available

The European Space Agency (ESA) has released the Sentinel-2A orthorectified products.

Images are available for free at this link https://scihub.copernicus.eu/s2/ . Dozens of images are already available covering different parts of the world (acquired during the last few days), and in a few weeks the satellite should cover the whole world. In fact, Sentinel-2 is in the Ramp-Up phase that will bring data acquisition to its full capacity.

The following is a very interesting video by ESA Web-TV that illustrates the characteristics of this new satellite.

The following table illustrates the Sentinel-2 spectral bands.

These images with 10m spatial resolution will be extremely useful for environmental monitoring and applications related to agriculture, forestry, or urban planning.

In the following weeks I am also going to update the Semi-Automatic Classification Plugin for QGIS in order to adapt the tools to the products of the Sentinel-2 routine phase.
